WEATHER-STRIP.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed March 6, 1905- Serial No. 248.382.

To all whom it may concern.-

Be it known that I, SAMUEL P. BRIOKER, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inWeather-Strips, of Which the following is a specification, referencebeing had therein to the accompanying drawings, forming part of thespecification, in which Figure 1 is a perspective detail view of aportion of-the plow member of my improved weather-strip. Fig. 2 is asimilar view of a portion of the tongue member. Fig. 3 is a view similarto Fig. 1, showing a modified construction. Fig. 4 is a crosssectionalview of a portion of a window frame and sash provided with theinterfitting plow and tongue members. Fig. 5 is a similar view showing amodified form of the tongue member. Figs. 6 and 7 are crosssectionalviews of Figs. 1 and 2, respectively. Fig. 8 is a sectional view of aportion of the sash-frame, showing a further modification of the tongue.Fig. 9 is a sectional view of the plow member set against a facing orlin-- ing strip.

My invention relates to weatherstrips, and refers more particularly tometallic devices of this class adapted to be secured to the window frameand sash, respectively, and to cooperate with each other to make a tightweatherproof interfitting engagement.

The present invention is designed to provide a stationary plow memberhaving a plurality of projecting single thickness ribs and anintermitting movable tongue member arranged to project between saidribs, although it will be understood that the different members of thedevice may be transposed with relation to the frame and sash, ifdesired, while the invention may also be adapted to any other meeting orinterfitting construction where it is desirable to obtain a practicallytight stationary or sliding joint.

The parts forming the strips are composed of thin metallic plates,preferably zinc or other non-corrosive material, so bent as to providethe projecting embracing rib portions, While being capable of a limiteddeflection to compensate for any irregularities in alinement, thicknessof the metal, &c.

Referring to the drawings, A represents the plow member, which issecured upon the inner sides of the frame by nails or screws, consistingof a base portion 2, bent or re doubled upon itself, as shown at 3, andthen bent outwardly at right angles to said base 2, providing a rib 1. Asimilar rib 5, having an L-shaped base portion 6, is inserted by meansof such base between the main base members 2 and 3 and is preferablyrigidly secured thereto by any suitable means, as by riveting,soldering, or by a series of punctures 7, thus incorporating the partstogether in one practically integral strip. As thus constructed anintervening space 8 is provided between the ribs 4 and 5, and for thepurpose of making interfitting engagement therewith I provide the tonguemember B, (shown in Fig. 2,) composed of an L-shaped strip of metal 9,provided with a base-flange by which it may be nailed to the sash withina receivingroove.

In Fig. 5 fhave shown the tongue member as made by simply doubling themetal upon itself, providing a doubled wall or tongue 11, set into thesash and secured by any suitable means, as small nails 12, the doubledtongue interfitting between the flanges 4 5 in the same manner asalready described.

In Fig. 8 I have shown a modified form of tongue member consisting of astrip of metal doubled to provide a central doubled tongue 9 withredoubled sides, providing intervening spaces 10 10, adapted to receivethe ribs 4 5, similar to the construction shown in my prior patent, No.712,761.

In Fig. 3 is shown a modified construction of the plow member whereinbut a single strip of metal is employed, doubled upon itself, as shownat 14, to provide abase, which may be of any desired width, the edges ofthe strip being then bent at right angles to said base portions, asshown at 15 and 16, provid: ing projecting ribs with an interveningspace 17, arranged to receive the tongue member, as in the constructionabove described. In Fig. 9 the same construction is shown set upon alining or facing strip of metal placed against the runway of thesash-frame. If desired, the strip may be secured to the lining strip inany convenient manner. Such a lining is desirable, as it provides abearingsurface for the edges of the sash and facilitates the operationof the window.

It will be understood that as thus constructed the interfitting plow andtongue members will engage each other and form a tight weatherproofjoint well adapted to the exclusion of the elements. A particularadvantage in the interfitting construction is that it overcomes theobjections of warpage, shrinkage, or expansion of the wood, providing adurable and reliable weather-strip which may be installed and left inplace during all seasons without interfering with the operation of thesash, While being capable of ready removal of'the sash or renewal ofsashcords, &c. A further advantage of great importance is that allrattling or lateral movement of the sashes isentirely prevented byreason of the engagement of the stationary and movable members with eachother, and these advantages will be appreciated by all those accustomedto the use of metallic weatherstrips.

It will be understood that I do not desire to be confined to the eXactconstruction shown and described, but that variations therefrom may bemade by the skilled mechanic Without departing from the scope of thefollowing claims.

That I claim is 1. In a weather-strip, the combination of a primary baseof suitable metal bent upon itself to form a secondary base with itsterminal edge portion bent outwardly at right angles to form aprojecting rib, and a similar rib having its base incorporated with saidprimary base and secondary base and arranged parallel to saidfirst-named rib, substantially as set forth.

2. A weather-strip consisting of sheet metal refleXed upon one side onlyto provide an attaching-base and having its terminal edge portions bentout at right angles thereto and arranged in parallel relation to eachother with an intervening space, substantially as set forth.

3. In combination, a window-jamb, spaced strips applied to said jamb andforming a runway, a sash mounted in said runway and having a slot in aside thereof, and a weatherstrip comprising a base disposed in therunway and having its opposite edge portions engaged by the spacedstrips aforesaid, one edge portion of the base being folded thereon andthen projected outwardly to form a body portion, the outwardly-projectedbody portion being received in the slot of the sash aforesaid.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL P. BRICKER.
